Description (last modified by simonpj)
f = \p\q.body x = scc "foo" f (\y.e)
shows f having arity 2, and hence x having arity 1. But when we inline f, we get
x = scc "foo" let p = \x.e in \q.body
and the cheap-and-cheerful arity discovery function (exprArity) detects arity of 0, not 1. And then CoreLint complains about the inconsistency of arity and strictness info.
This is unpleasant but not actually a problem.
It shows up in the conc052 test (in the stm package).
Part of #1546 might be the same problem.
